PHPStan Namespace Constraints Rule
==================================

[](#phpstan-namespace-constraints-rule)

This repository contains the code for the namespace\_constraints rule for PHPStan.

Why?
----

[](#why)

In the most architectures you should not depend on everything. With this rule you can ensure that a source namespace (RegEx Pattern) can only depend on code that lives in the target namespaces.

Installation
------------

[](#installation)

```
$ composer require --dev mintware-de/phpstan-namespace-constraints
```

Configuration
-------------

[](#configuration)

Add this to your `phpstan.neon`

```
# phpstan.neon
includes:
    - vendor/mintware-de/phpstan-namespace-constraints/src/Rules/rules.neon

parameters:
    namespace_constraints:
        constraints:
            - from: 'App\\SourceNamespace(\\.*)?' # Everything inside this namespace has access to
              to: ['App\\SourceNamespace(\\.*)?'] # this namespace
```
